Serial Optical Coherence Tomography Findings After Lesion-Preparation Incorporating the ShockFast™ Intravascular Lithotripsy: A Prospective Single-Center Imaging Sub-Study

Background

Intravascular lithotripsy (IVL) is an established calcium modification strategy for severely calcified coronary lesions. The Shunmei ShockFast™ IVL system is a novel device that appeared safe and feasible in an initial clinical experience. However, its calcium fracture typology, depth distribution, and quantitative stent optimization characteristics have not been characterized by serial optical coherence tomography (OCT).
